A specimen pair, one of red-brown hematitic jasper, and a vuggy light brown matrix with prismatic white jackstraw cerussites, with inked label reading: 'cerrusite, Pentireglaze, Dec 22nd, 169'. 220 grams total, 63-73mm (2 1/2 - 3"). Ex Dr M. G. 'Sam' Weller, MBE, collection, Cornwall, UK; from Cornwall, UK, supplied with Dr Wellers personal collection labels. Dr Maurice G. Weller, MBE, Ph.D, FISC, traded for many years as 'Sam Weller Minerals' following an interest held from the age of 12 years when he inherited a 19th century family collection; he was a member and sometime President of the Royal Geological Society of Cornwall and a member of Cornwall Archaeological Society (born Cornwall, 31 March 1931"). He had joined the RAF as a young man and spent 22 years in developing sophisticated military radar technology (for which he was awarded his MBE) until he medically retired in 1969, after which he established Yonder Town Field Studies Centre in Newquay, Cornwall before moving to Pendeen. Sam has now decided that the time has come to part with his private collection of minerals, including a number from historic Cornish sites, some with 19th century pedigrees. [2.
